Windows 7: Cannot connect to internet without Static IP

I have been googling about this problem that I have been having for over 2 hours, but to no avail. Ever since I upgraded my previously windows vista computer up to windows 7, I have been having severe problems connecting to my home internet. Now, I cannot change any of my routers settings since they are my stepfathers ,and he has a set username and password that I am not allowed to know. All other device in our house will connect just fine to our internet, and my laptop can connect to all other routers fine, this one is the only one I have problems with. What happens is that I get a "connected with limited access" error, and am completely unable to gain any internet access. I managed to set some static IP settings that allow me internet access, yet make things run more slowly and I am unable to connect with people properly in game, such as hosting a terraria server and other things like it.
These are my computer specs:
Windows 7 Ultimate Service Pack 1
AMD Athlon(tm) X2 Dual-Core QL-65 2.10 GHz
3.00 GB RAM (2.75 GB usable)
32-bit operating system

I have attempted uninstalling and reinstalling the network drivers, and when I troubleshoot problems when I'm not using the static IP, it says there is a problem but gives little to no information, while being unable to automatically solve the problem.
Let me make it clear that when I was on windows vista, my connection was fine, and I still connect to every other network I try fine without the static IP.
I have attempted to use ipconfig /remove and ipconfig /renew also to no avail, and I am really not sure what else I can do.

The static IP allows me connection to the internet, but I am tired of it being slow and giving me trouble with connectivity.

Could anyone help? I have posted on forums about my problem, but nowhere have I managed to find any REAL help.

I know that it's not because of Hamachi, since like I said, It has been doing this ever since I upgraded my operating system. When I upgraded, I did not keep any of my old files, I just started from scratch. I will see about disabling hamachi though, hopefully it will have an impact.

Alright, I attempted the fix that you gave me, and at the same time disabled hamachi. After the computer restarted, I was still unable to get a connection to my internet without a static IP, it came up as "unidentified network". I know that my hamachi now does not come up as an unidentified network like it did before though, which I'm sure means that it did something good.

I'm sure you realize that DHCP is disabled for your wireless connection, I assume this is because DHCP wasn't working?

It might help to remove everything static in the IPv4 properties window like the static DNS server's which can by typed into the routers DNS server settings instead. Resetting the router would be worth trying at this point.

About the only other thing I can think of is that it's a driver problem in which case going to the actual manufacture's site of this machine or the maker of the adaptor and obtaining an updated version of the driver might be worth while.

I made sure to remove all my static IP settings before trying to connect to the internet when i tried, and my result is posted in my previous post. It might be something up with the router, but that doesn't explain why this is the only device having problems connecting to it.
